We sketch recent progress in the title fields, including progress in understanding the abstract structure of Hamiltonian theories of balanced motion, the so-called ``slow manifold''. Here a generic phenomenon, ``velocity splitting'', turns out to be intimately related to aerodynamic sound generation, particularly to its generalization which describes spontaneous emission of inertia-gravity waves from unsteady vortical motions in stratified rotating flow.
